* Compatibility issues: Most modern diesel engines, including those in Range Rovers, are designed for ultra-low sulfur diesel (ULSD). Biodiesel, especially B100 (100% biodiesel), has different properties and can cause compatibility issues with the engine, fuel system, and seals. This can lead to:
* Fuel system damage: Biodiesel can degrade seals and rubber components in the fuel system.
* Engine performance issues: Biodiesel can cause problems with fuel injectors, fuel pumps, and other engine components.
* Increased wear and tear: Biodiesel can increase wear on engine parts due to its higher viscosity.
* Fuel stability: Biodiesel is less stable than ULSD and can degrade over time, leading to fuel system clogging and engine problems.
* Cold weather performance: Biodiesel can solidify in cold weather, making it difficult to start the engine.
However, there are some exceptions:
* Blends: Many modern diesel engines are compatible with blends of biodiesel and ULSD, such as B20 (20% biodiesel, 80% ULSD). However, it's crucial to consult your owner's manual or a qualified mechanic to confirm compatibility.
* Older models: Some older Range Rover models may be compatible with higher blends of biodiesel, but it's important to research thoroughly and check with a mechanic before using it.
Alternatives:
* B20 blends: This blend is widely available and often compatible with modern diesel engines.
* Renewable diesel: This fuel is derived from renewable sources and is chemically similar to ULSD, making it compatible with most diesel engines.
Before using any type of alternative fuel in your Range Rover, consult your owner's manual or a qualified mechanic for specific recommendations and compatibility information.
